You can do it using localtime and printf or POSIX::strftime. POSIX is a core module. FYI POSIX::mktime converts sec,min,hr,d,m,y to epoch time if you want to go the other way.

my $time = time();
my ($sec,$min,$hour,$day,$mon,$year) = localtime($time);
$year+= 1900;
$mon += 1;
$year = substr $year, 1;
printf "%02d/%02d/%02d %02d:%02d\n", $year, $mon, $day, $hour, $min;

use POSIX qw(strftime);
print strftime("%y/%m/%d %H:%M\n", localtime);

print strftime("
POSIX strftime
a %a
A %A
b %b
B %B
c %c
d %d
H %H

U %U
w %w

x %x
